The last new episode of Castle for 2009 will be airing on December 7th (don't worry, it returns early in January). Mark Blucas (of Buffy fame) will be making a guest appearance. I love how the ABC showrunners keep making references to former Whedon shows and characters. Check out the three sneak peeks below and then take a look at the promo photos I posted previously.
